Looking for a longer-lasting battery

[crazeinc]

I just picked up a used Vaio PCG-FRV26 laptop for a nice deal, but the only thing that sucks is the battery life appears to be not much over an hour from a full charge. I did a little snooping around and it looks like if I just bought a new battery that it would only give me around 2 hours. Is there an aftermarket battery I could use with my Sony that could give me like 3-4 hours or is there nothing like that that exists?

Thanks,
PJ

There is probably no replacement battery that has higher capacity, but you can get external battery systems that hook up the AC adapter. Those batteries in turn charge your main battery and from what I hear give you 5-8 hours of extra battery life.
IIRC, the FRV26 is a P4 notebook, right? I would find a new battery on eBay if possible, otherwise check pricewatch.com and just search for the battery under the make & model of the laptop.
